A lot of people are wondering why Nokia didn't choose to go with Android. How can Nokia differentiate themselves when Android is a lot more open and free than Windows Phone 7? As usual, the key to this is in the details. If you read the announcements carefully, you'll see that Microsoft offered Nokia something Google most likely didn't. Update: What a surprise. Elop just confirmed Nokia has a special deal with Microsoft. Whereas HTC, Samsung, and so on are not allowed to customise WP7 - Nokia is, further confirming my theory.

You say that they will get to influence the future development of phone 7 more than with android. Why is that a good thing for nokia or microsoft? The whole reason they are in this position is that they were not able to make good decisions about ther own OS. So now they get to mess up microsoft's also? (Here I take your word for it not beeing messed up already). And that is supposed to be better, how?

Stock fell 10% today, not because the market thinks phone 7 is bad, but because this proves that nokia could not create a good os in 5 years of trying, that is really bad when looking at android and webOS.
